This study aimed at analyzing the effect of 5S practice on staff motivation, patients' waiting time and patient satisfaction with health services at hospitals in Uganda. Double-difference estimates were measured for 13 Regional Referral Hospitals and eight General Hospitals implementing 5S practice separately. The study for Regional Referral Hospitals revealed 5S practice had the effect on staf...

The effects of ribosomal proteins L18, L25 and L5 on the conformation of 5S RNA have been studied by circular dichroism and temperature dependent ultraviolet absorbance. The circular dichroism spectrum of native 5S RNA is characterized in the near ultraviolet by a large positive band at 267 nm and a small negative band at 298 nm. The greatest perturbation in the spectrum was produced by protein...

In Xenopus somatic cells, the somatic-type 5S RNA genes replicate early in S phase, bind the transcription factor TFIIIA, and are expressed; in contrast, the late replicating oocyte-type genes do not bind TFIIIA and are transcriptionally inactive. These facts support a model in which the order of replication of the somatic-type versus the oocyte-type 5S genes causes their differential expressio...

The rates of synthesis of ribosomes, 5S RNA, and tRNA necessary to maintain the steady-state concentrations of these entities in liver cytoplasm of adult rats were determined. On the average, each liver cell in the adult rat synthesizes 650 ribosomes, 650 molecules of 5S RNA, and 11,000 molecules of tRNA each minute. The numbers of genes per liver cell for rRNA, 5S RNA, and tRNA were 330, 1660,...

Mammalian mitochondrial ribosomes contain two prokaryotic-like rRNAs, 12S and 16S, both encoded by mitochondrial DNA. As opposed to cytosolic ribosomes, however, these ribosomes are not thought to contain 5S rRNA. For this reason, it has been unclear whether 5S rRNA, which can be detected in mitochondrial preparations, is an authentic organellar species imported from the cytosol or is merely a ...

A Xenopus borealis somatic 5S RNA gene was assembled with either the complete octamer of histones, (H2A/H2B/H3/H4)2, or the (H3/H4)2 tetramer of histones that comprises the central protein kernel of the nucleosome. Gel-mobility shifts, DNase I protection, and immunoblotting assays demonstrate that the class III transcription factor IIIA (TFIIIA) readily interacts with 5S DNA associated with the...

In small oocytes of Xenopus species, two sets of 5S RNA genes, oocyte-type and somatic-type, are fully activated. The 5S RNA transcripts are temporarily stored, half in association with TFIIIA to form a 7S particle, the other half in association with tRNA and two proteins (p48 and p43) to form a 42S particle. It has been established previously that TFIIIA binds to the internal control region of...

Footprint competition assays are utilized to study the binding of Xenopus transcription factor A to a variety of single-stranded nucleic acids. The addition of Xenopus oocyte, yeast, or wheat germ 5S RNA as footprint competitors reveals that factor A binds these 5S RNAs with similar affinity. In contrast, factor A does not bind to E.coli 5S RNA or wheat germ tRNA in this assay. Factor A binding...

In eukaryotes, three of the four ribosomal RNAs (rRNAs)—the 5.8S, 18S, and 25S/28S rRNAs—are processed from a single pre-rRNA transcript and assembled into ribosomes. The fourth rRNA, the 5S rRNA, is transcribed by RNA polymerase III and is assembled into the 5S ribonucleoprotein particle (RNP), containing ribosomal proteins Rpl5/uL18 and Rpl11/uL5, prior to its incorporation into preribosomes....

A partial knockout compensation method to screen 5S ribosomal RNA sequence variants in vivo is described. The system utilizes an Escherichia coli strain in which five of eight genomic 5S rRNA genes were deleted in conjunction with a plasmid which is compensatory when carrying a functionally active 5S rRNA. The partial knockout strain is transformed with a population of potentially compensatory ...
